If modern laptop models are no longer equipped with disk drives, since the need for them is significantly reduced, then how to install Windows 7 without a disk and without a flash drive? As soon as it comes to reinstalling Windows, many begin to think that it would be better. But in fact, to reinstall Windows it is not at all necessary to have a disk drive, because you can install a new operating system using an external flash drive and even a database on it.

There is, of course, more than one way to install Windows 7 without a disk or flash drive. These methods are quite simple and understandable if you understand them. And so let's go.

1st method: Installing Windows without external media using the System Rollback utility

This standard method can be used if you have any problems with the OS. The utility loads well and responds normally to given commands. A system rollback involves returning the Windows state to the working state, that is, the one that was in the beginning.
Actions:

1 – Open “Start” -> “Control Panel” -> “Recovery”.

2 – The “System Restore” window should appear; to continue working and start the recovery wizard, click the “Next” button. After this, the wizard will provide you with a choice of a Windows 7 recovery point. Select the option based on the date of normal operation of the OS and click the “Finish” button, and then continue again using “Next”.


The operating system rollback is basically complete; the rest of the work will be done by the recovery wizard itself. This method is very simple and straightforward, and it does not change information that already exists on the device.

2nd method: Installing Windows 7 without external media using Recovery

If there are problems with the OS, and it does not start, then an effective solution would be to use Recovery.

Recovery is a utility that is a built-in module in most modern laptops. On different laptop models it may have a slightly different name, but its purpose is the same - to return the Windows version to the factory one. That is, this method will be relevant only for those who had Windows 7 official.

1 – Start the Windows installation. In order to open the Recovery utility, you must restart the system and press the hotkey before it starts loading. This hotkey differs in different laptop models; it can be F4, F8, F9, F11, Dell and others.
2 – You will see a program window of the Recovery utility. On the main window, the program provides you with a choice of actions on the OS. Select "Recovery".
3 – The “Full Restore” window will appear, which will display the original state of the PC, backup date, source, etc. You select (in the first column) the state of the PC that needs to be returned and click the “Next” button.
4 – Then a warning window will appear, informing you that all information from the PC will be deleted and asking you to confirm the launch of OS recovery.
5 – And at the end a window will appear showing the progress of the Windows 7 recovery process.

If you still think that installing an operating system is an activity for computer technicians, then you are seriously mistaken.

Using this guide, you can install Windows 7, even if you are a novice PC user. So, let's get ready first.

1. Open "My computer" and see in which partition your system is currently installed.
   Remember its size and name so that you can find the volume you need during installation.
2. Collect in advance on a flash drive or other disk all the necessary drivers for your computer or laptop. If there is no disk with drivers, they can be downloaded from the official website of the equipment manufacturer. If you don’t do this, you risk being left without the Internet after installing the new system.
3. Which Windows 7 bit depth should I choose? Click « Control Panel -> System and Security -> System»
   
   If your computer or laptop has more than 3 gigabytes of RAM installed, it is definitely worth installing the 64-bit version. In general, we recommend installing x86 only on weak or very outdated hardware in the 21st century, after all :). Please note that the drivers for the same device are different; in fact, these are two different systems!
4. Download the Windows 7 installation ISO image:
   

   What are these images?

   These are original MSDN images downloaded from the official Microsoft website. The only change is that the ability to select the system edition during installation is unlocked. No files are affected and the system is not activated.
   Other versions of Windows 7 images can be downloaded.
   

5. Prepare a bootable USB flash drive with Windows 7. In this guide, we will install the system from a flash drive because it is faster and easier. Similar instructions on how to create it can be found.
6. Since during installation we will format the disk with the installed system, all important files stored on it must first be copied to removable media or to another partition of the hard drive. Remember that files located on the desktop are also stored on the system disk. If you need them, be sure to move them to another place. When formatting, all previously installed programs will be deleted, but this does not mean that they also need to be copied to flash drives and disks. It's easier to reinstall programs, so only worry about – photographs, documents, music, etc.

Create a bootable USB flash drive using . Next, insert it into the USB port and change the boot priority in the motherboard BIOS so that this flash drive boots first. If difficulties arise at this step, here are detailed instructions. If you did everything correctly by changing the boot priority, then after exiting the BIOS and restarting the computer, the message “Press any key” will appear on the screen. Fulfill this requirement - press any key to start booting from the installation media.

You only need to press the key ONCE and only at this stage of installation.

After pressing any key, a message will appear indicating that Windows is downloading files.

System installation

So, let's proceed directly to installing Windows 7. Wait until their extraction is completed, after which the installer start window will appear on the screen. Congratulations, the hardest part is over!

1. Select your language, time format and layout. Click "Next".
2. Click on the big button "Install" to start the installation wizard.



Attention!

Note: choose the version of Windows for which you have an activation key (you will enter it at the final stage of installation). If there is no key, read the instructions after installation.

3. Read the license terms and accept them.
4. Select the full installation (updating is not suitable for us).
5. After starting the full installation, the partition selection screen appears. The installer window will have several sections: First usually reserved by the system (recovery files are stored in it). It weighs 100 MB and does not need to be touched. Second is a system file - that is, Windows files are stored on it. A new system is being installed on it. Third section – file. User data is stored here and remains intact even after reinstalling Windows.
   There may be other options: for example, there is no system-reserved partition or there is no volume with user files. In any case, you need the partition on which the previous system was already installed - it’s not for nothing that when preparing for installation, we advised you to look and remember its size.
   If for some reason you still have one partition, the volume of which exceeds 250 GB, then it is better to immediately divide the disk into two volumes: one for Windows and programs (approximately 50-100 GB), the second for personal files. To do this, using the “Disk Setup” tool, delete the existing partition and first create the first volume (“Create” - specify the volume - “Apply”), and then the second.
   

   The created volumes must be named “Partition 1”, “Section 2”. There should be no unallocated space left - the system simply will not see it.

   So, you have at least two partitions, one of which is dedicated to operating system files. If it has not just been created, but has already been created before, then it needs to be formatted by deleting all data.
   Click on the link "Disk Setup", highlight a section and press "Format". When formatting, all files on the system partition will be deleted (that is, the values ​​in the “Full size” and “Free” columns will become the same). This is exactly what we wanted. To start a clean installation, click "Next", checking again that the partition you allocated for the system is highlighted.

6. We are waiting. After selecting a partition and starting the installation, a window will appear on the screen in which you can see the process of unpacking Windows 7 files and writing them to the hard drive. While you can rest, you won’t have to do anything for 15-25 minutes.
   During this installation time, the computer will reboot several times. After the installation is complete, you need to specify some system operating parameters.
   
7. Enter computer name Computer name The computer name is what your computer will be called on the local network. and username. It is advisable to use Latin characters instead of Russian, this will help avoid problems with some programs in the future.
   
8. You can set an administrator password if you wish, but this is not necessary. If you set a password, you will need to enter it every time you start your computer or laptop. We will leave the field empty for now; you can “password” your account later.
   
9. Enter your activation key if you have one. If there is no key, uncheck "Automatically activate" and skip the step by pressing "Next".
   
10. Specify Windows settings - it is better to select the recommended settings, when you get to know the new system better, configure it in your own way.
    After selecting all the necessary parameters, the Windows 7 desktop will appear on the screen. You can begin your acquaintance with the system, but first reboot the computer and go into the BIOS again - here you need to change the boot priority back, putting the hard drive in first place.
11. Turn on automatic system updates and wait until the process completes. Security updates will install most drivers. If there is no Internet, you can use a program to install drivers .

The instructions turned out to be quite impressive in volume, but now you know the main nuances when installing Windows 7 and can easily do it yourself. Carefully follow the above recommendations and the installation will definitely be successful.

How about without a disk? This topic is relevant today. Moreover, it concerns the new OS developments that appeared not so long ago. And now in more detail! Windows 7, or simply “seven,” is one of the latest operating systems from Microsoft, and at the same time the most successful of them. At least that's what many experts think.

What does installing from a boot drive mean?

7 without disk? The standard model for installing any operating system is from a hard drive. And in addition to a disk, a drive can be used as it. The installation option from a flash drive is quite reliable. As with a disk, the host system is installed at a lower level in the computer's software hierarchy. In other words, "from under the old system." In addition, this method of loading a new “OS” allows you to format the hard drive on which the previous system was located. This will protect the OS from old programs that may be malicious, as well as from “under-deleted” parts of files that are invisible at first glance, but remain in the system and interfere with its normal operation. Such “scraps” of unnecessary documents hinder the speed of the system. Malfunctions may occur. You should consider how to reinstall Windows 7 without a disk and without a flash drive.

If there is neither a flash drive nor a disk

The standard installation method is not always possible. For example, if there is no disk, but there is an OS file on the computer or laptop itself. What to do in such a situation? How to reinstall Windows 7 without a disk or flash drive on a computer? The system file can be presented in the form of an image, an archive, or simply an installer. To install the system from an image, you must run a special program. It is necessary for reading/writing exactly this kind of formats. For example, Daemon Tools. Having launched the image in the program and mounted it, you should select the installation file. If the OS is available as an archive, then there is no need to unpack it. How to reinstall Windows 7 without a disk or flash drive on a computer in such a situation? Click on the archive and select the installer file in It has “.exe” permission. This file is located mainly towards the end of the list of archive contents. There will be no difference in launching the installer even if the operating system is simply located in some folder.

What do you need to remember?

If you are installing a production system for the first time, there are some rules to keep in mind. You need to know them if you need to answer the question of how to reinstall Windows 7. Whether this will be done without a disk or with it does not play an important role.

Firstly, the installation of a new OS may occur due to the computer being infected with viruses. This is a useless process if it is not accompanied by formatting. The fact is that infected files do not disappear anywhere with this type of installation of the main working environment. They are saved in the previously installed system. Subsequently, they will simply switch to a new shell.

Secondly, the best, and most importantly, the safest installation method is still to use a hard drive. Reinstalling Windows 7 without a disk in such a situation is not difficult. It is enough to have a bootable USB flash drive. If it does not exist, then it is created using simple actions. There is a program specifically for this that writes images to media. For example, Ultra ISO. Accordingly, if the files are not in disk image format, you should create one. Usually the same Daemon Tools is used for this.

How to reinstall Windows 7 without a disk on a laptop or computer? It should be remembered that when installing a new system, you should always use only verified files. The fact is that with modern progress, handicraft assemblies are found everywhere. When downloading Windows 7 from the Internet, no one can say with confidence that it is not “hard-wired” with malicious software.

First actions

How to reinstall Windows 7 without a disk on a laptop or computer? Let's look at how to do this in the simplest way. Find the folder with the operating system, launch it. After this, the installation window will open. It will display the ability to configure the following settings:

• selecting the system language (this is the language of the displayed names of folders, files, disks, and so on);
• keyboard layout (input language);
• time format (country, time zone).

For our country, naturally, you should choose the Russian language option everywhere.
After clicking the "Next" button, a window with the "Install" button opens. By clicking on the installation, go to Accept it by checking the box next to the appropriate inscription.

The most popular types of systems

The installer may contain several system options. The most commonly used:

• home - for an inexperienced user;
• standard - for those who confidently work with a computer;
• professional - for an experienced person; it offers extensive capabilities, necessary modules and great access to files;
• maximum - provides full access to all functionality of the operating system.

If you are wondering how to reinstall Windows 7 without a disk or flash drive on a laptop or computer, then you should understand that this is an incomplete list of possible systems.

Don't forget about the bit depth

All programs of this type differ in their bit depth, that is, 32-bit (X86) and 64-bit (X64). This parameter is indicated after the system name. For example, Windows 7 Ultimate X86.

The choice of the level of the system to be installed should be made based on the power of the computer's resources. If your laptop or PC is relatively weak, it is recommended to install X86 OS (32-bit version). It is best to install Windows 7 X64 if the RAM size exceeds 4GB. The thing is that the 32-bit version is simply unable to “see” such a volume.

What to do when formatting is needed?

Let's get back to how to reinstall Windows 7 without a disk. The next OS installer window will offer the option to complete it on your computer and update. You must opt ​​for a full installation. Otherwise, only an update to the pre-existing operating system will occur.

After selecting the preliminary parameters, a window appears with the ability to select a hard drive. This method will not allow you to format it. This is due to the fact that the installer was launched from a running system. If it is necessary to format the disk, which is desirable when installing the OS, then this point can be bypassed. This happens as follows. Until the new “seven” is installed, take any other partition of the disk and clear it of files (move them if you need them, and just don’t touch them if you don’t need them). After that, format the partition. You should not change the drive letter in this situation. When answering the question of how to reinstall Windows 7 without a disk or flash drive on a laptop or computer, you should keep in mind that when you boot the new system, the drive letters will change automatically. The formatted partition should be selected for system installation.

If cleaning is not needed

If formatting is not necessary, you can simply select the drive to install the new system and continue. In such a situation, the old system will remain in the "Windows old" folder. It will be located on drive "C". It will also be possible to start and work from it. But it is not recommended to do this, since two identical operating systems on the same disk may “conflict”. This, in turn, will lead to a malfunction. The old OS can be removed or moved to another medium. There is another very significant point that you should remember when answering the question of how to reinstall Windows 7 without a disk on a laptop from Asus, Lenovo, HP, etc.

If the partition on which the new OS is installed does not have enough space for two operating systems, the installation process will not be able to start. This occurs due to the fact that the old shell is not removed and continues to occupy space. It is important to remember that frequent reinstallation of the operating system leads to disk destruction. This can be avoided by using different types of defragmenters. For example, the Victoria program.

This problem is not so bad for computers. There is nothing easier than buying a new hard drive and installing it. This is easy to do yourself. However, if the hard drive breaks on a laptop, then, in addition to the cost of the disk itself, you will have to pay for repair services. You should know about this if you are interested in the question of how to reinstall Windows 7 without a disk from a flash drive.

What do you need to enter after installation?

Having selected the disk (partition) for installation, click “Next”, which will lead to unpacking and subsequent installation of the new Windows 7. This process is fully automated. It will last for 25-30 minutes, depending on the power of the computer (laptop). After completing the installation, you need to enter the following parameters:

1. Username (your own name or a desired nickname).
2. Computer name (any name in Latin or Russian letters).

If the input is incorrect, the system will tell you about it and ask you to correct the symbols, indicating the error.

Entering the password and key

During installation, you will be asked to assign a password and a hint in case you lose it. After this, a window appears in which you must enter the key to activate the operating system. If it is missing, simply click “Next” after unchecking the box next to “Activation while connected to the Internet.” Then you will be able to activate the system in any convenient way. This is done as follows:

1. You need to find the "My Computer" folder.
2. You need to open it by clicking the right mouse button.
3. You need to click on the "Properties" tab.
4. You should select the “Change product key” option.

You need to protect your computer from external threats

Let's return to the question of how to reinstall Windows 7 without a disk on a computer or laptop. The next step is the security settings. You can use the recommended service, or you can postpone the decision and configure it later. Protecting your computer is one of the most important aspects of installing an operating system. The fact is that the security of the equipment will depend on how well you limit access parameters from other people’s devices. This menu is nothing more than offering an option to select a data protection set created by Microsoft specialists. It should be understood that they already provide and set the recommended parameters. By skipping this point, many people forget to perform the configuration manually in the future, putting their files at risk.

So, having decided on security, click “Next” and set up the time and date (time zone, etc.) in a new window.

Next, the installer displays the network parameters window. It can be either home or public. Due to this, the settings in the Internet properties are changed. As for the general understanding, the home network looks more conservative regarding the configuration. A public network, on the contrary, provides greater access to the resources of a laptop or computer.

What can be changed after installation?

This was the last step, after which you will get a practically empty desktop of the newly installed Windows 7 operating system. Basic settings (for example, adding the My Computer folder or user files to the desktop) can be done by left-clicking on the desktop space and by selecting the "Personalization" tab.

There you can also set a different background image, change the default theme (usually Windows 7 Aero), change the screen resolution, and much more.

Standard licensed Windows 7 comes without additional programs. However, among the numerous assemblies you can find options that include many additional elements, software, and so on.

Conclusion

This article described how to reinstall Windows 7 without a disk or flash drive. You will install it on the computer - it does not play a big role. The principle of the installation process for a new system is the same.

A situation often arises when the issue of reinstalling the operating system becomes urgent. Let's take a specific case. There is a laptop purchased with Windows 7 already pre-installed. Windows itself is still, one might say, in working condition, but the user is quite worried about some circumstances. What exactly? Due to external virus attacks, as well as during operation, errors accumulate over and over again, which leads the computer to a rather slow boot process, and other software tools are not pleasing with their previous performance. At the same time, cleaning the registry, anti-virus measures and returning to a previously recorded recovery checkpoint do not give the expected results. There is only one way out - reinstalling the system. How does this process happen?

It is worth noting that a laptop with a pre-installed system is good because its manufacturer took care of the operating system distribution, which is stored in a hidden section of the device’s hard drive. Drivers and source programs are also located there. All this provides an excellent opportunity to reinstall, if there are good reasons for doing so. There are two specific situations. If things are really bad and the system does not want to start, then the recovery starts by pressing a certain key when turning it on. What it is depends on the specific manufacturer. You can find it out in the user manual.

But our case is different - the OS is in working condition. Let's proceed step by step to reinstalling Windows 7 without a boot disk or flash drive.

Step 1. Click the Start button and launch Control Panel. If it is in the “Categories” viewing mode, then you should go to “Large Icons” or “Small Icons”. In this case, it is easier to find the “Recovery” tab.

Step 2. Let's open it. We are interested in the very bottom option “Advanced recovery methods”.

Step 3. Let's launch it. A window appears reminding you that when you restore the system partition, which is usually the entire working disk, all data and documents created by the user will be erased.

Care and accuracy should be exercised when copying all necessary data onto storage media (disks, flash drives, external USB drives).

If the data has been copied in advance, you should press the “ Skip“, then the computer will prompt you to reboot, which will start the system installation process.

At the bottom there is a button “ Exit” in order to return to the system again before installation to continue copying important information.

Step 4. After successful completion, Windows will have factory settings and the original programs when you purchased the laptop. By the way, you do not need to enter the serial number of the licensed software and activate it. All this, in most cases, is already integrated into the actual installation process. The user can only install the software he needs and configure the desktop at his discretion.

As can be seen from this short instruction, the process of reinstalling Windows 7 without a disk or flash drive does not require special knowledge and is available to everyone completely free of charge. Anyone can handle it if they are careful and attentive.

If for some reason you were unable to install Windows 7 yourself, you can contact us for help or try.
